Andy Shevchenko 20d9b3b5f2 gpiolib: sysfs: Do unexport GPIO when user asks for it ...

It seems that sysfs interface implicitly relied on the gpiod_free() to
unexport the line. This is logically incorrect as core gpiolib should
not deal with sysfs so instead of restoring it, let's call
gpiod_unexport() from sysfs code.
